ABOVE NORMAL TEMPERATURES. A COLD FRONT APPROACHING FROM THE EASTERN
GREAT LAKES REGION AND SAINT LAWRENCE VALLEY MONDAY NIGHT INTO
TUESDAY WILL BRING SCATTERED SHOWERS TO THE REGION.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
FOR TONIGHT...EXPECT ANY LINGERING DAYTIME INSTABILITY SHOWERS TO
END EARLY THIS EVENING...SO WILL LEAVE SLIGHT CHANCE POPS IN
THROUGH THAT TIME PERIOD. OVERNIGHT EXPECT MAINLY CLEAR SKIES WITH
GOOD RADIATIONAL COOLING AS HIGH PRESSURE REMAINS ANCHORED OFF THE
NEW ENGLAND COAST. LOWS OVERNIGHT WILL BE IN THE UPPER 30S TO MID

THE SAINT LAWRENCE VALLEY MONDAY EVENING INTO THE CENTRAL PORTION
OF OUR FA BY TUESDAY MORNING AND THEN OFF THE SOUTHERN NEW ENGLAND
COAST BY LATE TUESDAY. EXPECT SCATTERED TO NUMEROUS SHOWERS AHEAD
OF THE COLD FRONT WITH THE GREATEST LIKELIHOOD OF SHOWERS AHEAD
OF THE COLD FRONT ACROSS THE NORTHWEST PORTION OF THE FA. HAVE NOT
PLACED ANY THUNDER IN THE FORECAST AS THE MLMUCAPES ARE ONLY A FEW
HUNDRED J/KG AT MOST AND THE SHOWALTER INDICES REMAIN POSITIVE
DURING THE PERIOD OF PRECIPITATION ACROSS OUR FA. EXPECT LOWS

TUESDAY IN THE UPPER 60S TO MID 70S.

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE PERIOD TRANSITIONS FROM DRY TO SHOWERY...WITH WELL ABOVE NORMAL
TEMPERATURES.  HIGH PRESSURE GRADUALLY BREAKS DOWN...AND A WARM
FRONT LIFTS ACROSS OUR FORECAST AREA DRY FRIDAY NIGHT.  THE INFLUX
OF MOISTURE WILL BE LIMITED...THUS SOME SOUTHERN ZONES MAY NOT SEE
ANY PRECIPITATION DURING THIS PERIOD.  THE CLOSING IN PROXIMITY OF A
COLD FRONT FROM THE NORTHWEST WILL...HOWEVER...INCREASE POPS...
BRINGING US OUR GREATEST CHANCES FOR SHOWERY WETTING ON SUNDAY.
CAPES AND OTHER INDICES ARE TOO WEAK TO SUPPORT THUNDERSTORM
ACTIVITY.

DAYTIME HIGH TEMPERATURES THROUGH THE PERIOD WILL AVERAGE FROM
AROUND 70 TO AROUND 80 DEGREES.  LOWS START OUT WEDNESDAY NIGHT
MOSTLY IN THE 40S...THEN /MILD UP/ INTO THE MID AND UPPER 50S BY

REGION TODAY. DAYTIME HEATING IS RESULTING IN SCT-BKN CU IN THE VFR
RANGE (6000-8000 FEET) ACROSS THE REGION FOR THE REST OF THIS
AFTERNOON...ALONG WITH ISOLATED RAIN SHOWERS. HAVE GENERALLY LEFT
